The thought briefly crossed Fang Zheng's mind before he packed it away.
Indeed, the Followers of the Crimson Realm were formidable, and the Fire Mist Warriors were strong, but they were powerless in front of the Zerg. However, Fang Zheng would not resort to this method unless absolutely necessary. Once he summoned the Swarm to this world, it would signify an invasion of this world, and by then, except for Tilia, everyone else would likely become his enemy.
Fang Zheng certainly had no intentions of becoming the target of a collective attack. Besides, turning Earth into a Zerg colony was not beneficial, was it? This was not the world of Ironblood Warriors, and its aesthetics were still acceptable; after all, aesthetics are righteousness.
What other methods then were there to achieve his goal... Wait a moment!
At this, Fang Zheng suddenly remembered something.
